\ Itisan object of 1the-inventionto provide a lead pencil lsharpeneridevice, `the l'parts `oflwhich are so `constructed and cooperatively arranged that itheymay be readilysecured'toor removed fromfan end opalead pencilifor protecting against breakage `of a sharpenedi point of the pencil at times whenrthe Sharpener andpencil `arenot in. use, `saidrlevice further being constructed so that ioI thepencilois accurately centered axiallyof the device during a sharpening of `the writlng lead of thepencil. l l r Another object of the invention isto provide a device for said purposes, the parts of which are so constructed and arranged that said parts, together with the lead pencil, may be secured together, at `times when* said device andpencil are i secured to the clothing ofthe user whennot in use for preventing loss of the pencil and said de-` vice.

a device having a cutter which may be readily removed for a replacement or sharpening of the blade thereof. f Other and further objects and advantages of the invention will be obvious fromthe following detailed description thereof. l i In the drawing: Figure 1 is a sideelevation of thenew device A further object ofthe invention is to provide i i cal sleeve I3, having an open end III and a closed end uI 5, `the interior `of the latter `being .of conical shape inlongitudinal section 1and of circular shape in cross section,` as shown in Figure 4. Each end ofthe sleeve is preferably `provided with anan nular reinforcing `ferr'ule I6, whereby the `sleeve I3 may be oflightrweight material.

The sleeve may bemouldedzof any onefof sev-` eral Asuitable plastic materials, vand asV best shown in Figurell; the end ofythe. wall of the conicall portion I5 at the apex of said conical` wallfis provided with an opening Ilrincommiunicaton with i al bore I8, `whereby. at :times when the pencil is inserted into the conical portion I5, the pointed end I I of the pencil `is received in the boreV I8 forl protecting said pointed end against breakage at times when the pencil is stored and not in use.

An end of thesleeve adjacent the bore I8 is preferably provided with a recess I9 for snugly receiving therein a member 2|] formed of rubber, said member being suitable for mark erasing Durposes.

The wall of the conical portion of the sleeve I3 is provided `with an opening 2I across which a cutter 22 is disposed. The sleeve I3 is further i provided with an outwardly disposedlug 23 having and showing a fragment, of a lead pencil attached thereto for storing the pointed end of a pencil Within the new device.

Figure 2 is a planview showing the point of the pencil in a writing or reverse position with respect to the showing thereof in Figure 1.

Figure 3 is a transverse section` taken approximately on line 3-3 of Figure 5.

Figure 4 is a longitudinal section of the new device, a resilient clipemployed being omitted.

Figure 5 is a view similar to Figure 1 and showa flange 24 against which one end of the cutter 22 is `disposed in use. Adjacent the bore I8, the sleeve is provided With a kerf 25 for receiving therein the otherendof the cutter.

As best shown in Figure 3, a detent or screw 26 is disposed through the aperture 21 of thecutter 22, said screw being `threadedly engaged in the lug `23 for preventing movement of the cutter transversely with respect to the sleeve, said flange 24 and kerf 25 preventing swinging movements of the cutter to an undesired extent.

As thus described, it will be noted that the sharp elongated cutting edge 21a of the cutter 22 is normally held at an angle complementa] to ing the new device turned at an angle of approxi- `mately 180 degrees with respect tothe showing thereof in Figurel.

Figure 6 is a perspective blade employed.

view of a cutter or In the drawing, a conventional lead pencil is `generallyindicated` at I0 having a stick of lead graphite axially disposed with respect to and within the casing of the pencil. The lead is provided with a sharp writing point H` at the end of the wooden reinforcing casing I2 thereof. As is well known, the graphite lead is fragile, easilybro-ken,

` and becomes worn away through use.

the conical shape of the portion I5 of the sleeve for pencil sharpening purposes.

In order to sharpen the lead pencil, the pointed end of the latter is inserted into the sleeve, the new device being held inthe ngers of one hand of an operator while the latter rotates the penci1 with his other hand, pressing the pencil toward the rubber 20, whereby shavings from the pencil i pass outwardly through the opening 2I.

The new device further includes an elongated resilient clip 28, having an end 29 which is rigidly secured tothe sleeve by any suitable means. If

desired, theclip 28 `may be formed integral with the sleeve as shown in Figure 1.

As best shown in Figure 5, the clip is of arcuate shape in side elevation, preferably being provided with a ball 30 at the free end thereof, said arcuate shape providing a space 3| between the At times when the pencil and new device are to be transported about the person of a user, the pencil and new device are joinedl together by means of the clip 28, as shown in Figures 1 and 5, and the end of the lead pencil, which includes the rubber 20, is inserted into a vest pocket of the user in a manner whereby thel cloth adjacentI the edge of said pocket extends into the space 3l, the ball 3l] of the clip at this time being urged toward and against the inner surface of the cloth of the pocket, and pressing the outer surface of the cloth against the lead pencil-in a manner whereby the writing point of the pencil is not only protectingly locked to the new sharpening device, but is also cooperatively locked to the clothing of the user for preventing loss of the pencil and the new device during transportation of said items and at times when said items are not in use.

From the foregoing description, it is thought to be obvious that a pencil Sharpener and-holder constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptiblev of some change and modification without departing from the principles 'and spirit thereof and for this reason, I do not wish it to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as claimed.

I claim:

1. A device for the purpose `described comprising a molded plastic sleeve having an open end and aclosed end, a slot disposed longitudinally through a side wall of said sleeve, said sleeve having flanged portions adjacent said slot ends, a cutter seated in said flan-ged portions, and means removably securing said cutter to said sleeve.

2. A device as claimed inclaim 1 inwhich the closed end of the sleeve is provided with a bore.

3. In a device of the character described a non-metallic membenhavingl a recess of conical shape at one end thereof, a slotdisposed longitudinally through a side wall of said member, a lug adjacent one enfof said slot, a'ange on said lug, a kerf at the other end of sai-d slot, a cutter extending into ,said recess through said slot, said cutter having one of its ends seated beneath said flange and its other end in said kerf, and fastening means removably securing said cutter to said lug.
